. CONDUIT-7MACHINET'T A pplie ation flled Marcl,1 16, 1910'. smart. Manda To all whom it may concern Be it known that We, and-EDIA RLRAMSEY, citizens of the United States of America, and residingat Penn Yam in the county of Yates" and State of New York, ,have invented certain new and useful Improvements in Conduit Machine's,

of which the following is, a. specification,

such as will enable, those skilled in the art to which it appertains to make and use the same. I

This invention relates to the manufacture of that class of conduits formed by successive layers of suitable-material wound spirally, one over another, aridpreferably in reverse direction, and the object'thereof is to carrying the material, in rolls, about a I wmdin'gs,

ception of a provide-a machine" fqrthis purpose which employs a. stationary mandrelyupon which mandrel and the said' casing."

A further object is to provide accessible tension devices for each of the said materials when a conduit is-heing formed there-. with.-

' A further object is to provide means for causing the said rolls of material to revolve in reverse directions about the mandrel. I

A further object is to provide means for automatically sliding the conduit, when wound,,.- along the mandrel, between revolutions of the said rolls of material; a further obj-ectbeing to provlcle such last named do:

' the inner wall into close contact with eachv .other and in.-t he same plane.

vices which force the successive windings ot 'A further object is to insure the superimposed winding at a slight distance from the inner winding and also to provide means whereby the :said outer windingwill overlap in the successive turns to lock the same, the said means being also adjustable 1n a degree to determine the amount of said 1 1p and the, angle or pitch of the turns; and a still further object is to construct such a JEROME S. WHEELER" machine which issim'plein construction {and operatlon, as well as rap1d,'-and: comparatively inexpensive.

Our invention is fully deseribed'in the following specification, of which -the accompany ng drawings for-m a part, inwhich the separate parts v are designated by the-same reference characters in each of the views, and in, which Figure 1 is a side elevation of our inven-- tion ready for use, and showing a part of the product; Fig. 2 is 'a section on the line 2-2 of Fig. 1 Fig. 3'is a sectionon the line 3-3 of Fig. 2; Fig. 4 is an end view in the direction of the arroww; Fig. 5 is an en larged view of a detail in section; and Fig. 6 is aseotion on the line 6 6 of Fig. 5.

In the drawings forming a partof this application we have shown a 'base aupon which are mounted two supports a? and (13-, the former of which carries a transverse shaft (1 having two. bevel gears a, and a secured thereon of different sizes, and a .pulley (2. adapted to be driven by a belt/a Rotatable in the support a is a longitudinally arranged sleeve Z) having a bevel pmion 6 secured'thereon by means of a screw If and enmeshed with the gear a5, the said sleeve alsocarrying, at its opposite end, a. disk I) secured by means of a screw b,fand' the disk b* carries a metal yoke 0 having a stub shaft 0*" at the outer end thereof upon which are. mounted washers 0 0 and c and a nut c for holding a roll of suitable mate- RAMSEY, or PENN-IAN, nnw' onx, nssrenons 'ro Specification cf Letters Patent.

the nut 0 serving as a tension device for the tape 0 in the feeding thereof,

lotat'able within the sleeve 7) is alonger sleeve (lyto which is secured abevcl pinion (Z by means of'a screw denmeshed with the gear a, and the sleeve (Z also carries a casing (1* secured byineans of a screw d,

said casing carrying a roller (2 and being provided with a removable cover at held by wing-nuts (1 At 6 we have shown a shaft secured in the support (t by means of a screw e adjustably, against rotation, and extending through the sleeve (1 to a point adjacent the position of the casing d, and to which is secured a mandrel e having an enlarged angular portion 13' adjacent the said shaft 0 1") and into which it enters and is secured means of a screw threaded part- 6", thus libiding said mandrel stationary, and the mandrel is provided with a flange 6 for'reasons j hereinafter explained.

Slidably mounted about the mandrel e s acasing f having a removable cap 5 provided with a nosing f preferably incliiied, and. with a lug f on one side thereof and normally held closelyadjacent the cover of the casing or drum (1* by means oi a spring f extendingbetween thefliange e Q passes through an aperture k in the side'of the drum (Zf*,.thence over the roller (5 and through a guide, 11, on the cover all and w'hich is provided with av tension plate h. held adjustably'bymeans of a screw it and.

' which time the friction tapec is placed on The wound portion ofthe fiber strip andis wound thereon by the revolution of the 5 5 yoke 0,. this start being made manually but the subsequent operation is automatic as will be seen. i

Byreference to Fig. 1 it will be seen that the fiber strip k is narnower than the friction tape 0" the reason for which is that it is desired to butt the turns of the former, as clearly-shown, but to lap the latter, as also shown, the friction tape have been previously coated With adhesive .natter whereby (l5 the-successive turns adhere to each other as from the other, and it will be seen that the one and the cover a? for the other.

at all turns, and this movement of the casing 35 1 also forces the completed conduit rearwardly alongand oil of the mandrel for a corresponding distance and thus automatirally removing the conduit, step by step,

after completion. .As previously stated, the friction tape turns are some distance to the rear of the fiber turns, one. reasomforwhich is that an imperfect condition of the latter may be seen before being covered by the 1 latter, and another being that time is thus 5 given for the insertio of cord, tape, or the like, around the said .windings, alternately,' toserve as binders therefor and prevent the" wi'lt'ul or accidental stripping-thereof, one
